The exactness of saccadic eye movements to the right and to the left and changes in evoked potentials related to these eye movements were analyzed in 50 university students with marked righthandedness and normal vision, aged from 18 to 24 years (18 males, 32 females). The saccades to the left were found to be more exact than those to the right, which overshot the target in a significantly higher number of instances. In subjects with exact refixations the premotion activity in evoked potentials is of shorter duration, the spike potential has a lower amplitude and the lambda response a shorter latency in saccades to the left. The given changes are more pronounced above the right occipital region. In subjects with a higher number of correction saccades the differences between the two sides disappear in saccade related evoked potentials. The obtained results support the presumed important role of the right hemisphere or the left half of the visual field in organizing eye movements and in the integration mechanisms of eyemotion-visual perception in righthanded subjects.
对50名年龄在18至24岁（18名男性，32名女性）、明显右利手且视力正常的大学生，分析了其左右眼扫视运动的精确性以及与这些眼动相关的诱发电位变化。结果发现，向左的扫视比向右的更精确，向右扫视时明显有更多情况会超过目标。在具有精确再注视的受试者中，诱发电位的运动前活动持续时间较短，在向左扫视时，尖峰电位振幅较低，λ反应潜伏期较短。上述变化在右枕叶区域上方更为明显。在具有较多校正扫视的受试者中，与扫视相关的诱发电位两侧差异消失。所得结果支持了右半球或视野左半部分在右利手受试者眼动组织以及眼动 - 视觉感知整合机制中假定的重要作用。
